应用SPECT局部脑血流（rCBF）断层显像方法，依据ROI比值测定法，测定34例优势半球脑出血患者急性期、亚急性期rCBF比值。结果失语组局部脑血流灌注显著减少（P＜0．01），而且失语程度恢复良好，脑血流灌注恢复亦明显（P＜0．01），表明局部脑血流与失语有关。
SPECT regional cerebral blood flow (rCBF) tomography was used to determine the ratio of rCBF in acute and subacute phase in 34 patients with dominant hemisphere cerebral hemorrhage according to the ROI method. Results The aphasia group had a significant decrease of cerebral blood perfusion (P <0.01), and the degree of aphasia recovered well. The recovery of cerebral perfusion was also significant (P <0.01), indicating that local cerebral blood flow was related to aphasia.
